I have a 73 ford that has a 360 in it. It get fuel and fire but won't start and stay runing we have put new spark plugs,spark plug wires and it still won't start? Ant thing helps let me no if you no what is rong

I agree with Jim. I have a 1976 F250. You can do the old-fashion way of testing to see if you have spark, with a helper, stick a screwdriver in a spark plug wire and hold the stem of screwdriver near the tip of plug and have somebody crank the engine. If you see a nice cobalt-blue spark, that's good. If you see a yellow-ish spark that is a weak spark. And tap on the carb to make sure the float is not stuck. Otherwise, all Jim said.

The RPM's fluttered and it died. The PCM code read that it was the crankshaft sensor.
We have checked the following:
coil - replaced
fuses - good
control module (ecm) - replaced
plug wires - replaced...
